Estudio de la variabilidad genética inducida por el genotipo mutador de cloroplastos de la cebada a través de la técnica de TILLING
(Departamento de Fisiología, Biología Molecular y Celular, Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2018-11)El aislamiento de mutantes inducidas en el plastoma a partir de tratamientos con mutágenos químicos y/o físicos es muy poco exitoso. El genotipo mutador de los cloroplastos de la cebada (cpm) es único en monocotiledóneas ... -
Estudio de variables biológicas ante un desafío artificial de L3 de H. contortus en dos majadas de ovinos Corriedale
(Asociación Argentina de Producción Animal, 2022-11)H. contortus es uno de los parásitos que ocasiona mayores problemas en regiones templadas, tropicales y subtropicales debido a pérdidas productivas y económicas. La utilización de drogas es fundamental para el control de ... -
Estudio del proceso de apropiación por patentes de la tecnología de transgénesis vegetal en Argentina. Una visión desde las reivindicaciones

Estudios regulatorios para las evaluaciones de riesgo de los cultivos transgénicos : un análisis preliminar
(Facultad de Agronomía, Universidad de Buenos Aires, 2022-06)Los desarrollos tecnológicos vinculados con los organismos genéticamente modificados (OGM) hicieron necesaria la implementación de sistemas regulatorios destinados a garantizar la seguridad ambiental y la aptitud alimentaria. ... -
European research priorities in farm animal genomics
(University of Zagreb, 2013-09)Production of safe and healthy high quality food for human population, preservation of stable rural social economic infrastructure and sustainable use of agricultural land and animal resources are important goals of European ... -
Evaluating mating compatibility within fruit fly cryptic species complexes and the potential role of sex pheromones in pre-mating isolation
(Pensoft Publishers, 2015-11)The study of sexual behavior and the identification of the signals involved in mate recognition between con-specifics are key components that can shed some light, as part of an integrative taxonomic approach, in delimitating ... -
Evolution of pre‐zygotic and post‐zygotic barriers to gene flow among three cryptic species within the Anastrepha fraterculus complex
(Wiley, 2013-09)Tropical tephritids are ideally suited for studies on population divergence and speciation because they include species groups undergoing rapid radiation, in which morphologically cryptic species and sister species are ... -
Expansion of the basic knowledge on the inheritance of characters that allow the development of new maize brreeding techniques = Expansión de los conocimientos básicos de la herencia de caracteres que posibiliten desarrollar nuevas técnicas de mejoramiento en maíz
(Sociedad Argentina de Genética, 2023-07)In order to increase the efficiency of maize hybrid seed production it is necessary to achieve a high grain yield to reduce production costs. This goal requires an expansion of the basic knowledge of the inheritance of ... -
Exploring the ancestral mechanisms of regulation of horizontally acquired nitrogenases
(Springer, 2015-10)The vast majority of Pseudomonas species are unable to fix atmospheric nitrogen. Although several studies have demonstrated that some strains belonging to the genus Pseudomonas sensu stricto do have the ability to fix ... -
Exploring the Intrinsic Limits of Nitrogenase Transfer from Bacteria to Eukaryotes
(Springer, 2013-08)Biological nitrogen fixation is widespread among the Eubacteria and Archae domains but completely absent in eukaryotes. The lack of lateral transfer of nitrogen-fixation genes from prokaryotes to eukaryotes has been partially ... -
Expression analysis of genes putatively associated with hygienic behavior in selected stocks of Apis mellifera L. from Argentina
(2017-11)Hygienic behavior is an economically beneficial, heritable trait, which has evolved to limit the impact of honeybee pathogens. Selecting and breeding colonies with high levels of hygienic behavior has become a feasible and ... -
Fine mapping of LrSV2, a race-specific adult plant leaf rust resistance gene on wheat chromosome 3BS
(Springer, 2014-05)Three leaf rust resistance genes were identified in the durable leaf rust resistant Argentinean wheat variety Sinvalocho MA: the seedling resistance gene Lr3 on distal 6BL and two adult plant resistance genes, LrSV1 and ... -
Fruit infestation patterns by Anastrepha fraterculus and Ceratitis capitata reveal that cross-recognition does not lead to complete avoidance of interspecific competition in nature
(Wiley, 2015-08)1. The avoidance of parasitized or infested hosts, which is a common phenomenon in parasitic wasps and phytophagous insects, may act both intra- and interspecifically. Most studies on chemically-mediated avoidance of ... -
Generalized glycogenosis in Brahman-derived breeds: diagnosis and prevalence in Argentina
(Springer, 2019-08)Generalized glycogenosis is a lethal autosomal recessive disease caused by a deficient activity of the acidic 1,4-α-glucosidase enzyme and characterized by an accumulation of glycogen within lysosomes. Three mutations in ... -
Genetic analysis of environmental strains of the plant pathogen Phytophthora capsici reveals heterogeneous repertoire of effectors and possible effector evolution via genomic island
(Oxford University Press, 2015-11)Phytophthora capsici is a virulent oomycete pathogen of many vegetable crops. Recently, it has been demonstrated that the recognition of the RXLR effector AVR3a1 of P. capsici (PcAVR3a1) triggers a hypersensitive response ... -
